Potential Interference To The Proposed Radio Telescope Employing The Decommissioned 21m Diameter Earth Satellite Station At Kuntunse, Ghana -2015 To 2018
For the radio telescope to function properly, the surrounding areas must be free from interferers, especially at the Ku band of operation. It will be laborious to manually keep scanning the radio space for potential interferers, which is why we researched into developing a system to help with interference studies for the radio telescope project.
Noise Parameters Extraction Using Variations Of The 6-Port Network – 2010 To Date
Conventionally, the noise parameters for a linear two-port device-under-test (DUT) are measured using a mechanical impedance tuner. The mechanical impedance tuner is used to vary the source impedance seen from the DUT. An experimental search for the minimum noise figure using the mechanical impedance tuner results in the optimum impedance too. One or several nonsingular noise figure measurements then result in the complete determination of the noise parameters. The noise parameters determined by this technique generally show fluctuation and are inaccurate. Commercial test set are ridiculously expensive. This research employs a six-port network to find alternative noise parameters measurement technique that will be fast, accurate, simple and at very low cost.
